TXT is a DNS record, containing data in human-readable form for external sources to gain information about a certain Internet domain or subdomain. In the most common situation, this kind of record is used to prove that you own a domain name if you are trying to add it to a search engine or to some traffic analytics platform. Considering that only the domain owner/administrator may add custom DNS records, the TXT record serves as a verification of ownership for the business providing the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) security, that makes sure that a particular email address isn’t spoofed and that others will not get junk mail from allegedly your mailbox. The TXT record includes info about the mail server where your online messages originate from and serves as confirmation that it's a trusted one. Because there are no restrictions concerning the content of this type of a record, you can add any other info as well.
